Rage (Ex)

A dire wolverine that takes damage in combat flies into a rage on its
next turn, madly clawing and biting until either it or its opponent is
dead. It gains +4 to Strength, +4 to Constitution, and –2 to AC. The
creature cannot end its rage voluntarily.

ECOLOGY

Environment cold forestsOrganization solitary or pairTreasure none

Dire wolverines
tend to be even more territorial than their smaller wolverine cousins,
and they defend to the death the areas where they choose to live, often
selecting humanoid-settled regions as their own and then fearlessly
tearing the settlements apart. Dire wolverines grow to about 12 feet in
length and can weigh as much as 2,000 pounds.
